BACKGROUND

During a production process, a production workshop requires transport ofa variety of raw materials, semi-finished products and finishedproducts, and therefore uses warehouse carts and cargo containers.However, existing cargo containers can only be transported usingwarehouse carts, not by forklifts or cranes, which leads to a pooruniversal applicability. Moreover, those cargo containers cannot befolded, which leads to them taking up a large occupied space and makesfor inconvenient unloading.

SUMMARY

We have developed a cargo container design a that can be transported bya variety of transport devices, has a simple structure, occupies a smallspace, and facilitates unloading. Embodiments of our design can providethe at least some of the following advantages. Since two sides of thebottoms of the left frame and the right frame are all formed withrecessed support grooves, this enables transport of the cargo containerby means of a forklift, a dolly and the like, leading to stronguniversal applicability. With some embodiments, the left frame and theright frame include a suspension ring on the top, which enables thetransport of the cargo container using a crane, also leading to stronguniversal applicability. During unloading, the cargo container isplace-able on the unloading rack so that the unloading rack supports thegoods, within the cargo container. The left frame and the right framecan ten be rotated around the rear frame to open the cargo container upand, thereby, facilitates unloading. In addition, by virtue of thisfolding capability, when not in use, the left frame, right frame andrear frame can be folded together to greatly reduce the occupied spaceand facilitate the recovery of the cargo container.

One aspect of this disclosure involves a fast unloading folding cargocontainer having a left frame, a right frame, a rear frame, a bottomframe, and connection members. The left frame and the right frame arerotatably connected to the rear frame via the connection members. Bothends of the bottom frame are formed with locking slots that lock ontothe rails on the bottoms of the left frame and the right frame, bothsides of the bottoms of the left frame and the right frame includerecessed support grooves, and the left frame and the right frame bothinclude a suspension member on the top.

Other aspects of the disclosure involve the left frame, the right frameand the rear frame all having a rectangular outer frame and a number offrame support rails within the rectangular outer frame, and the bottomframe having bottom bars, and a number of base support rails, spacedapart from each other, on the bottom bars.

Still other aspects of the disclosure involve an unloading rackincluding base bars and a number of loading rails located on the basebars, so that the loading rails correspond to the spacing between thesupport rails.

Additional aspects of the disclosure involve a cushion layer on top ofthe loading rails.

Still further aspects of the disclosure involve a front rung, with oneend of the front rung rotatably connected to one of the left frame orthe right frame, and the other of the left frame or right frame isprovided with a locking member to which the front rung can lock.
